Using the ImageEllipse Function in PHP

PHP makes it easy to do many things needed on a website, including creating images. This can be useful for CAPTCHA images, or designing a banner or logo on the fly, as some free blogging software does. Information can be passed to functions through arguments, which are specified after the function name, inside parentheses. As with variables, arguments can be passed by value or by reference. It is essential to be aware of this, as it can affect how your code works and what type of return you will get.

The imageellipse function draws an ellipse centered at the given coordinates. The image argument is a GdImage object, returned by one of the image creation functions, such as imagecreatetruecolor(). The fill color is a color identifier created with imagecolorallocate(). The return value is either true or false.

In this article we will see an efficient method for achieving image upload in PHP, by using an HTML form, with the option to choose a file and a button to upload it to your server. We will also use a MySQL database to connect with the function that will insert the submitted file into your website.

To create our form we will need to set up a table with fields for the file name and an upload button, along with the PHP function that will do the work of uploading it. We will also use a CSS stylesheet to give the form some basic styling.
